SPECIFICATION forming part of Letters Patent No. 425,515, dated April 15, 1890.

Application tiled May 20, 1889. Serial No. 811,4=62. (No model.)

To @ZZ whom it may oon/cern:

Be it known that we, PATRICK J. LAWLER and JoHN F. BARRY, citizens of the United States of America, and residents of West Side, in the county of Crawford and State of Iowa, have invented certain new and novel Improvements in Corn-Harvesters, of which the following is a specieation.

Our present invention has relation. to improvements in that class of corn-harvesters known as strippers7 and huskers; and it consists in the construction, combination, and arrangementof parts, ashereinafterdescribed, pointed out in the claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation with parts broken away, and Fig. 2 represents a top view of our improvement with the yoke-frame removed. Figs. 3, 4, and 5 are enlarged detail views of different parts.

A represents a quadrilateral-shaped frame composed of two mating sections that are rigidly connected at their front portions by means of a yoke A4, that projects perpendicularly, as shown in Fig. 1, and as required to stride a row of corn, the sills of which are strengthen ed by means of suitable transverse braces, and that is provided at the rear with an auxiliary transverse frame A', as shown in Fig. 2. The frame is supported upon two wheels A2 A3. The wheel A2 is provided with a sprocket-wheel and a gearwheel,by means of which motive power is applied to the operating mechanism of our device. The lower supporting-sills of the main frame are provided at their forward ends with the triangular'shaped gatherers B B, which are preferably of metal, and are mounted so that they do not extend quite across the forward portion of the frame, but leave a suitable opening through which the cornstalk may pass.

O C are two cylindrical spiral conveyershaving cone-shaped bodies, each provided at its ends with suitable journals, one of which is adapted to work within a suitable bearing upon one of the transverse braces at the rear of the frame, while the other is adapted to work within a bearing of the gatherer, as shown by dotted lines in Fig. 1. The conveyers interlock and revolve inwardly and in opposite directions to one another. They are mounted slightly at an angle, so that the rear portions of the conveyors are slightly higher than the forward, as illustrated in Fig. l. The spiral portions of the conveyers do not extend quite the full length of the body portion, but end in a cylindrical portion, that extends belowand beyond the auxiliary frame A. At the rear the conveyors are provided with mating pinions C2 C2. The outer conveyer C is provided, in addition, with the sprocket-wheel C3, which is engaged by an endless chain, as described hereinafter.

Immediately above the cylindrical ends of the conveyors and mounted transversely thereto are two sets of husking-rollers, comprising the male rolls D D and female rolls D2 D2. These rollers work above the endless belt E, which works upon the cylindrical portion of the conveyer C, and at the other end upon a suitable pulley (not shown) at the extreme end of the auxiliary frame A. At their outer ends each set of husking-rollers is provided with a set of mating pinions,while the male rolls D D of each set are provided, in addition, with the sprocket-wheels D3 D3, which are engaged by the endless chain D1'.

E E are converging chutes, which are mounted above the endless belt E and have their vconverging points immediately in front of the husking-rolls, and are adapted to direct the corn carried upon the belt E to said husking-rollers, as will be understood by referring to Fig. 2 of the annexed drawings.

F F are two iron rods that rest upon the spiral conveyers and work within movable bearings at the front and rear of the frame. These rods serve as guard-rolls and keep the ears of corn as they are conveyed upward from working to the other side of the conveyers.

Gr G and G G are rollers that work in a perpendicular position and are mounted in brackets that extend above and to the center of the conveyers. The rollers are mounted in sets of two, each set being provided with a number of endless chains G2 G2, which work in line with the conveyers, as will be understood by referring to the gures. The rear roll of each set is provided with a sprocketwheel G3, which is adapted to be engaged by the endless chain G4, which works upon the sprocket G5 of the driving-shaft H. This shaft is mounted within bearings at the side of the IOO frame, and is provided at its lower end with a miter-gear H which engages the corresponding miter H2 of the transverse drivingshaft H3. able transverse braces of the frame, and is provided in addition to the miterI-l2 with a pinion (on the shaft H3, but not shown) which engages the gear-wheel J, xed to the drivingwheel A3, from which the shaft H3 receives its motive power.

K is a shaft that is mounted at right angles to the driving-shaft H3, and is provided with a ruiter-gear K in connection with the gear H2 from which it receives its motive power. At its outer end the shaft K is provided with a sprocket-wheel K2, which is engaged by the chain K3, connected to the sprocket-wheel C3 of the spiral conveyers C.

Connected to the side of the auxiliary frame is a shaft L, which is provided with two sprocket-wheels L L2. The wheel L is engaged by the endless chain M, which works upon the sprocket-wheel M of the drivingwheel A2, as shown in Fig. 2. The sprocket L2 is engaged by the chain D4 in connection with the sprocket-wheels D3 D3 of the husk- Aing-rolls D D.

The conveyers C C are operated as follows: As the machine is carried forward the gearwheel J rotates the pinion on the end of the vshaft H3, and that shaft, being geared to the shaft K, imparts rotary motion thereto and to the sprocket K2. The sprocket K2 is connected to the geared conveyer by means of the chain K3, and thereby imparts rotary motion to the conveyers, as will be understood by referring to Fig. l.

The husking-rollers are operated by means of the endless chains D4 and M, which latter is connected with a sprocket-wheel fixed to the Wheel A2.

The upright rollers G G are operated by means of the shaft H, which is connected at its lower end to the transverse driving-shaft H3 The shaft H3 is journaled to suitl and at its upper end by means of a sprocketwheel G5 and chain G4 to the rear rolls, as illustrated in Fig. 2.

The operation of our machine is as follows: The machine is drawn over a row of standing corn, which is led by the gatherers B B to the conveyers C C. As the stalks pass between the conveyers C C the ears are pinched 0E and carried upward until they fall upon the conveying-belt E. This belt carries the ears to the husking-rollers D D2, which tear the husks from the ears. The chains G2 upon the upright rollers prevent the stalks from lopping upon the conveyer, while the rods F keep the ears within the conveyers.

Having thus described our said invention, what We claim as new, and desire to secure by Letters Patent, iss-'- 1. In a corn-harvester, the reciprocating spiral conveyers C C, the guard-rods F F, working upon said conveyers, the endless belt E, working transversely to the said conveyers, and the husking-rolls D D2, workin g above the belt E, in combination with suitable supporting and operative mechanism, substantially as described.'

2. A corn-harvester composed of the mating frames A, connected by means of a yoke and mounted upon wheels A2 and A3, the cylindrical conveyers C, each having a fixed pinion C2, the chain-wheel fixed to one of the conveyers, the frame A', and the huskingrollers D D D2 D2, the converging chutes E and E, the rollers G and G", chains G2, the sprocket-wheel G3, and chain G4, andthe sprocket-wheel G5 on the shaft H, and mechanism for operating the shaft H, arranged and combined substantially as shown and described.
